There's currently a bug in Chrome giving SVG circles edges, making them look like stop signs.
https://code.google.com/p/chromium/issues/detail?id=395474
Does anybody know of a temporary workaround?

<div class="svg_wrapper">
<svg viewBox="0 0 600 425">
<path d="M 175, 175 m 0, -75 a 75,75 0 1,0 0,150 a 75,75 0 1,0 0,-150" fill="none" stroke="black" stroke-width="110"/>
